Pll Diagram. Here are photos of my pll. An incoming clock signal i clk.
The working of a pll is as follows. Here are photos of my pll. Figure 2 shows a block diagram of the cd4046b which has been implemented on a single monolithic integrated circuit.
In the basic pll reference signal and the signal from the voltage controlled oscillator are connected to the two input ports of the phase detector.
Pll circuits operate by comparing the phase of an external signal to the phase of a clock signal produced by a voltage controlled crystal oscillator vcxo. A 5 2 v zener diode is provided for supply regulation if necessary. An incoming clock signal i clk. Here are photos of my pll.
